(This would have been posted in the DIY board were there still just one DIY board.)

I was in Advance today at lunch and was surprised to find Mobil 1 0W40, 0W30 and 0W20. More amazingly, the price was just $3.98/qt. So I bought 12.

Just an FYI for you DIYers.

That really is a good price, do they have other weights as well?


There is a promotion at AutoZone stores on Castrol, buy 5 get 1 free. I just got 12 quarts of German made Syntec 0W-30, true synthetic @$4.16 a bottle.

They have the 5W30, 15W50 and maybe one or two others. But, as I use the 0W30 in my M3, I know I had never seen it there before. I've been stuck buying it at Mobil stations for something like $6.50/qt.

TD-

Thanks for the post. I use 5W30, but that price you gave is cheaper than what I normally get it for. Good to know.

M1 0W30, that's unusual, it's Mobil's one of the weakest oils, what made you to pick it? :dunno:

My understanding is that Mobil 1 0w-40 might be the best oil made for most BMWs. It meets Long Life 01, and euro A3, the very technical guys show it to have excellent additives, and Mobil is the first big manufacturer of synthetic oil. Unless something changes it's what I'll use after my warranty/free maintenance. Although the BMW(Castrol)5w-30, seems like it is very good oil (same spec) and very reasonable at $3.80/ us qt

Mobil1 0W-30 is a thin 30wt, 10.3 cSt@100C compared to let's say Castrol's 0W-30 with 12.1 cSt@100C and it is known to thin out even to 20wt. Oils that thin out of grade usually leave deposits behind. If I was to choose 30wt from Mobil1 it would be either 10W-30 or 5W-30 as they both need less Viscosity Improvers and are more shear stable.

From Mobil1 oils I would pick 0W-40, the only Mobil1 oil sold in US that meets both ACEA A3/B3 and BMW LL-01 specs.

Ironically, I picked up 0W40 for my next change.

JST and I were both at Curry's (was it last fall?) where we received an explanation of why the Mobil 1 0W30 was a better choice than the 0W40 from a Mobil rep (IIRC). I don't recall the exact details of the explanation (JST might recall better than I). It involved an explanation of how different weight oils "mist" and disburse to provide lubrication. 30 supposedly "mists" better than 40. Regardless, it was convincing and I bought it.

I've used the 0W30 for about a year (~ 3 changes). But I seem to "vaporize" it. I need to add a quart roughly every month to month and a half. I'm not visibly buring oil and my garage floor can attest to the fact that there are no leaks. That's why I want to try the 40.

I'm vaporizing 20W-50 (!) at a slightly less frequent interval. Not a leak in the world, it just disappears. :mad:

Yeah, that's what the guy said, but I don't really remember the technical side.

TD, you will be much happier with 0W-40, 40wt is what was initially intended for your S52. It will not only provide better protection over 0W-30 but your oil consumption will drop. Try to register how many miles you can go before you need to add oil, 1quart every 1,000 miles is nothing to worry about.

I have no idea what kind of "misting" this guy was talking about but I'm not an oil expert.
Thinner oils are sometimes recommended because they will flow and lubricate valvetrain elements a bit quicker, especially in cars with gear driven cams like some Toyotas. The only other reason why we see thin 20wt oil is CAFE but IMO running thinner oil to gain fuel mileage may compromise engine protection and longevity.

BMWs are known for their love of thicker oils and I'll never run 20wt in my car.
